What is current and types of current?
Wow, this could take all day depending on how deep you want to go! Current is the 'Juice' that flows through an electrical circuit. Current has been compared to water for explanation purposes. Voltage is the pressure that a system has, and current is the amount of water that flows through the system. A water tower is 100ft above the ground. Let's say that it has 100ft of pressure. This would be analogous to the potential difference (voltage). Water can flow through the pipes at 10 gallons per minute, in Electro-Speak; this would be the current (amps, amperage), particles of electricy per time unit, (particles/sec, particles/millisecond, etc.). In your house you have a lamp that operates a 120 Volts AC (alternating current, as opposed to DC - Direct Current like that in your car battery). The lamp is 120 watts (for ex.) therefore according to Ohm's law, the First Commandment of Electricity), the lamp draws 1 amp. Current (I) = Power (watts)/Voltage, Therefore 10 120w lamps = 1200 watts (like a hair dryer) draws 10 amps, a 60-watt lamp bulb would draw half an amp (0.5a). Current is also X# Coulombs per second, a coulomb is (whole bunch) of Joules/second. A Joule is a tiny particle of energy.
How much current is consumed for a tubelight which has 40W for domestic use?
In most of North America, the mains supply to the home is 120 volts. Thecurrent through a device dissipating 40 watts is 40/120 = 1/3 Ampere.In most of the rest of the world, the mains supply to the home is 220 volts.The current through a device dissipating 40 watts is 40/220 = 0.18 Ampere.
If Two galaxies are interacting with each other what is the force that draws them toward each other?
The force that draws two interacting galaxies toward each other is gravity. Gravity is the fundamental force of attraction between all objects with mass, including galaxies. This force can cause galaxies to merge or distort their shapes when they get too close to each other.
What draws water back to earth?
The main force that draws water back to Earth is gravity. It causes water vapor in the atmosphere to condense into clouds, and eventually fall back to the surface as precipitation like rain or snow. This continuous cycle of evaporation, condensation, and precipitation is known as the water cycle.
What draws dense rock away from Mid ocean ridges?
The process that draws dense rock away from mid-ocean ridges is called slab pull. This occurs due to the subduction of oceanic plates at convergent boundaries, where the dense oceanic crust sinks back into the mantle, creating a force that pulls the rest of the plate away from the ridge.
An electric iron always draws a current of 3.4 amp from the 220v supply line what current will this electric iron draws when connected to 110v supply line?
1.7amp
If electric heater works on 115 V and draws 3 A of current how much power does it use?
The formula you are looking for is W = I x E.
Why does electric bulb become dim when electric heater in parallel circuit is switched on?
The electric heater draws some of the electrical current in the circuit, which reduces the current available for the electric bulb. This leads to a decrease in the brightness of the bulb as it is receiving less power.
An electric motor draws a current of 11.5 A in a 240 V circuit What is the power of this motor in W?
11.5 x 240 = 2760W motor.
An electric lamp is rated at 60W the current it draws from a 230 V supply is?
P=VI so I=P/V I= 60/230 I=0.261 A
How does an electric car use electricity?
An electric motor draws current from the battery. The amount of current is determined by the position of the accelerator. Most vehicles use a pulsed DC current that is turned on and off depending upon the speed of the vehicle. A hybrid uses an engine that usually runs at a constant speed, charging the batteries as you go. The speed of the engine in the hybrid is usually set for about 35 mph. At this speed, you are drawing the same amount of current that the engine is supplying. At faster speeds, the electric motor draws more on the battery than the engine can supply for a limited distance at higher speeds.
How many watts of power does does an electric drill use when it is plugged into 120 volts and draws 10 amps?
Power = Volts * current [p = E*I]; 120volts*10amps = 1200watts
Does increasing the voltage to an electric heater increase the amperage it draws?
It will increase the current since the water heater is made of a heating element and which is resistive in nature. Ohms law states that V=IR where V is the voltage, I the current and R the resistance. Now the resistance will always remain constant. Thus, when the voltage is increased, the current will also increase.
What is the reason of when electric drill draw high current?
When an electric drill draws high current, it is typically due to increased resistance in the drill bit or the material being drilled. This resistance causes the motor to work harder to maintain the desired speed, resulting in higher current draw. It can also be caused by a dull or inappropriate drill bit, which requires more power to penetrate the material.
How much power in watts does an electric clothes dryer use if it draws 20 amps of current from a 240 volt wall outlet?
4800 watts because watts = volts x amps.
What is an example of electric current?
Here are a couple. Assuming everything is "normal" here, if you drop a bagel in the toaster and turn it on by pushing the lever down, the AC current the toaster uses (draws) will stabilize after a few seconds and stay constant. If you turn on your car's headlights, each lamp will draw a constant current from the DC source after a few seconds of "warm up" time. Those are examples of constant electric current.
A TV 220V 100W what is the current it draws?
100/220 = .45A or 450 mA
